T OLL WHOM IT CONCERN! i Be it known that SEAMN LLARE, of the city,jco un ty," a.nd --State of NewYork, have invented :t new fand useful Improvement in Hubs of CarriagofWheels; :1nd I do her'ebyvdeelare thzt the'ollowing is a full, clear, and exact description ot" the salme, reference being had to the accompanying-drawing,making a. portion of this specification, in which is'utransvl'se and longitudinal section o f a hub, inade :tccoi'ding'toonly n'vention,..as representediin sheetsl and 2. A T 1 In carriage-.wheels hayin'g hubs of ordinnryconstrnction, the spokes one very liubleto be loosened or broken 'at their jnnctionwith the hub, owing to the comparatively sliabtl depth of thosockets which receive the inner ends ,o f the spokes. I i

' The object of. this invcntiortis to provide .n rneas'of ohvintingvthis liability, and it consists in constructing thehub withucircnmferentialfseries of /slecves or' collars, wliehsyonstitute, as it were, extensionsor .continuaf tions'ofthe''sockets' formed 'in the hub/itself, and'which, by enabling the sockets to embraces. much greater length of the inne;l portions of the spokes than` would be possible ywithout such collars', v ciy materially increases the security with whichithe inner ends of the spokes are held infplace, dnd'thus electuellyv secures the desired resnlt,'. 4 l i Y -Y i To enable others toonderstand the noture undfconstruction of my invention, I will proceed to' describe itl with reference to the drawing.

` ''representsth'e hub, provided at snitble distances apart with radial sockets, a, of any z )rdinssr or appro- 'priste'form Provided upon Athe circumference of the hub, oneat the outer'end of each socket e, is oseries of sleeves or collars, 6,. which forni extensions or veont-inuzttions of the sockets, und the internal surfaces of"A which Ire made sloping, an'dnrranged to correspond and to `be continuous with thosc of the sockets a, :is represented.

in the 'drawing'.v The hub is made ci" cest metnl, with the sleeves oncollars cast in'onepiece`-v therewith'. 'The 'inner ends of the`sp'okes, one of which is shown at B, being made oi' a. suitable tapeiing'forin; areinserted through the sleeves or collars into the sockets e o fthe'hub, and, inasmuch-as the sleeves o1' c`olla1'sinsute n. much longer` bearing tothe inner ends, just mentioned, of the spokes, than would be-possible with the sockets alone, -itiollows that such ends are held with for greater security, and rendered much less liable to be broken, loosened, or injured at theirjunctiouwith the hub, than would be the case if the sleeves or collars were dispensed with.

--I do not claim the radially-extended mortises per se, as they havcbeenused in combination with parallel spokes, as in thepatent of B. A. Rogers, lo. 19,951, but

`'What I d claim 'as new, and desire to secure by Letters Patent, is-

The solid metallic hub A, provided with rad'ial sleeves b and wooden spokes B, Awhen constructed and com`r bined essentially as shown an'd described. v f
